Question

For what value of X is the perimeter of shape 77 cm? (x+1),(x_1),(x+2),(2x+2),(2x+1)​

Answer 1

Answer:

A] perimeter=77

⇒(x+1)+(x+1)+(2x+1)+(2x+2)+(x+2)=77

⇒7x+7=77

⇒x+1=11

∴x=10

Answer 2

Answer:

Perimeter= add all the lenght .

So ,

(X+1)+(x-1)+(x+2)+(2x+2)+2x+1)=77

7x+5=77

7x=72

X=72/7
